DOI: 10.1007/s00128-021-03254-z
Abstract: River water-column and bottom-sediments samples were screened for 160 pesticide compounds to compare the types of pesticides present in the water-column versus bottom-sediments, and between segments of rivers flowing through intensively-managed versus semi-natural habitats. Of… read more here.

DOI: 10.1007/s12665-018-7876-6
Abstract: The total mercury content of the surface layer (0–5 cm) of different types of bottom sediment in Gorky and Cheboksary reservoirs was determined. The content of mercury in bottom sediments varied within a wide range, 0.001–0.234 mg/kg.… read more here.
